gels_batch_scratchpad_size (Strided Version)
Computes size of scratchpad memory required for gels_batch (Strided Version) function. This routine belongs to the oneapi::mkl::lapack namespace.
Description
Computes the number of elements of type T the scratchpad memory to be passed to the gels_batch (Strided Version) function must be able to hold.
API
Syntax
namespace oneapi::mkl::lapack { std::int64_t gels_batch_scratchpad_size(sycl::queue &queue, mkl::transpose trans, std::int64_t m, std::int64_t n, std::int64_t nrhs, std::int64_t lda, std::int64_t stride_a, std::int64_t ldb, std::int64_t stride_b, std::int64_t batch_size) }
Input Parameters
- queue
-
Device queue where calculations will be performed.
- trans
-
Operation assumed to be done on input matrices Ai. Only trans = mkl::transpose::nontrans case is currently supported.
- m
-
The number of rows of the matrices Ai and Bi
- n
-
The number of columns of the matrices Ai
- nrhs
-
The number of right-hand sides: the number of columns in Bi
- lda
-
The leading dimension of Ai
- stride_a
-
The stride between the beginnings of matrices Ai inside the batch array a
- ldb
-
The leading dimensions of Bi
- stride_b
-
The stride between the beginnings of matrices Bi inside the batch array b.
- batch_size
-
The number of problems in a batch.
